CABINET
Side access panels shall be fabricated from 20 gauge
galvannealed steel and shall be securely bolted to a 14
gauge base and the top plate. The top plate, front and rear
panels shall be fabricated from 16 gauge galvannealed
steel. The cabinet shall be powder coated with a satin
black fi nish to provide durability, and to protect from
corrosion. Armafl ex elastomeric thermal insulation shall
be used to insulate the cabinet, block noise and prevent
damage from vibration. Casters and leveling feet shall be
included to ease the installation and level the equipment
with existing IT solutions.
AIRFLOW PATTERNS
All units shall be designed using a front discharge with
a rear return airfl ow pattern. An optional plenum with a
front diverted discharge pattern is available.
AIR FILTRATION
All units shall be equipped with removable, washable
fi lters. These fi lters shall consist of an open cell structured
polyurethane foam with a roll formed 3000 series
aluminum frame. Filters shall meet both UL 900 and UL
94 HF-1 standards.
MECHANICAL COMPONENTS
BACKWARD INCLINED, PLENUM STYLE FAN,
WITH AN EC MOTOR
The blowers shall be backward inclined plenum style
fans with an Electronically Commutated (EC) motor,
for maintenance free operation. The motor shall
include: integrated electronic control board and direct
microprocessor control signaling for fan speed control,
soft-starting capabilities, and integrated current limitations.
Each fan shall be low noise, low vibration manufactured
with an anti-corrosive aluminum impeller. Each fan
impeller shall be dynamically and statically balanced in two
planes to minimize vibration during operation.
CHILLED WATER COOLING COIL
The coil shall be constructed of seamless drawn copper
tubes, mechanically bonded to tempered aluminum fi ns
with enhanced fi n design for maximum heat transfer, and
STULZ CyberRow®
13 - 77 kW Row-Based
Precision Control Air Conditioners Chilled
Water Systems
SUMMARY
This specifi cation describes requirements for a precision
environmental control system. The STULZ CyberRow® is
a row-based cooling system that shall provide precision
temperature control (and humidity control for the
24” model) for computer rooms or rooms containing
telecommunications or other highly sensitive heat load
equipment where continuous 24 hour a day, 365 days a
year air conditioning is required.
Designed with both front and rear access, CyberRow®
systems require minimum fl oor space. The supplied system
shall be provided with ETL Certifi cation. The CyberRow®
model number shall be, CRS- - .
DESIGN REQUIREMENTS
The environmental control system shall be a STULZ
CyberRow® Chilled Water factory-assembled unit. The
unit shall be designed for a row-based installation with
removable front and rear access panels. No allowance for
side service access shall be required, however removable
side access panels shall be provided for additional access.
The CyberRow® units are especially adapted for both
raised and unraised fl oors. The air handling section shall
be specifi cally designed for high sensible heat ratio. Each
system shall be capable of handling CFM at inches
of water external static pressure. The unit shall have the
cooling capacity of BTU/H, and the sensible cooling
capacity of BTU/H based on entering air condition of
°F dry bulb and °F (°C) wet bulb. The humidifi er (only
available in the 24” unit) shall have the capacity of 5 Lbs/hr.
The main fan motors shall be HP. The unit shall have a
power supply of volts.
QUALITY ASSURANCE
The manufacture shall maintain a set of international
standards of quality management to insure product quality.
Each system shall be subjected to a complete operational
and functional test procedure at the factory prior to
shipment.
